Isolated Thoracic Aortitis

Immunoglobulin G4-related thoracic aortitis

Patients with immunoglobulin G4-related thoracic aortitis often have nonspecific symptoms, but pain in the chest or back is common. The rate of misdiagnosis of immunoglobulin G4-related thoracic aortitis is high, which may lead to mistreatment in extreme cases. A correct diagnosis should be based on comprehensive medical imaging, pathology, and laboratory and immunohistochemical results. Most patients' condition can be significantly improved using conservative or surgical treatment.

Acute decompensated heart failure as the initial presentation of isolated aortitis

Decompensated heart failure affects 5 million Americans and nearly 15 million individuals worldwide. Heart failure can be attributed to numerous etiologies, with autoimmune conditions representing a rare category of acute decompensations. Here, we report of case of a 66-year-old woman who presented with acute decompensated heart failure as a result of a rare vasculitis known as idiopathic aortitis. In addition to describing the case, we highlight the importance of proper ascending aorta evaluation in patients presenting with new onset heart failure, especially in the setting of aortic regurgitation. We use this case to discuss the entity of idiopathic aortitis, and review the literature on its clinical manifestations and long-term management.
